The present invention relates to a gear part mounting structure, in particular a gear part mounting structure for mounting a shaft part of a fishing reel to a gear part.

The fishing reel mainly includes a spinning reel and a double bearing reel. This type of fishing reel has a reel main body mounted on a fishing rod and a winding spool installed on the reel main body. Both of these bearing reels are rotatably supported by the reel main body, and are provided with a level winding mechanism for winding the fishing line evenly on the spool. In addition, the spinning reel is attached to the reel main body so as to be movable back and forth, and an oscillating mechanism for uniformly winding the fishing line to the spool is provided.

The level winding mechanism on both bearing reels engages a helical shaft disposed parallel to the spool shaft mounted on the spool, an interlock mechanism for rotating the spiral shaft, and a spiral groove formed on the spiral shaft to reciprocate and guide the fishing line. A fishing line guide part is provided (for example, refer patent document 1). The oscillating mechanism of the spinning reel also includes an interlocking mechanism interlocked with the rotation of the handle, a spiral shaft disposed in parallel with the spool shaft, and rotated by the interlocking mechanism, and reciprocating together with the spiral shaft in the spiral axis direction with the spool shaft. It is provided with the slider which became movable. Here, the fishing line is uniformly wound on the spool by rotating the spiral shaft by the rotation of the handle and reciprocating the fishing line guide and the slider. In addition, the interlock mechanism has a gear part provided to transmit the rotation of the handle, and the gear part is attached to one end of the spiral shaft so as not to rotate relatively. Specifically, the axial cross section of the distal end portion of the spiral shaft is formed to have a non-circular shape, a non-circular through hole penetrates the center portion of the gear component, and the distal end portion of the spiral shaft is engaged with the through hole of the gear component. This makes the spiral shaft and the gear part relatively ineligible.

In the above conventional level winding mechanism, the gear part is mounted on one end of the spiral shaft in a non-rotational manner, so that the spiral shaft can be rotated in conjunction with the rotation of the handle. However, since the distal end of the spiral shaft is only engaged with the through hole of the gear component, there may be a slight rattling between the distal end of the spiral shaft and the through hole of the gear component. Here, when the gear part is rotated by rotating the handle, in particular, when the rotational torque of the spiral shaft changes when the fishing line guide portion or the slider is returned at both ends of the spiral shaft, between the distal end of the spiral shaft and the through hole of the gear component. There is a concern that the rattling is increased and the feeling on the handle of the angler is lowered.

An object of the present invention is to suppress the deterioration of the sense of the angler's handle operation in the gear component mounting structure.

The gear part mounting structure of the fishing reel which concerns on this invention 1 is a gear part mounting structure used for the reciprocating mechanism of a fishing reel, and has a spiral shaft, a gear part, and an annular member. The spiral shaft has a shaft main body, a spiral groove formed so that both ends thereof are connected to intersect the outer circumference of the shaft main body, and a mounting portion provided at one end of the shaft main body. The gear part has a gear main body, a gear tooth formed along the circumferential direction of the outer circumferential portion of the gear main body, and a mounting recess formed by being recessed in the inner circumferential side of the gear main body, and in which the mounting portion is not rotatably mounted. The annular member is an elastic member that is remodeled between the mounting portion and the mounting recess.

In this gear component mounting structure, an annular member made of an elastic body is mounted between the mounting portion of the spiral shaft and the mounting recess of the gear component. No rattling occurs between the mounting recesses. Therefore, when the gear parts are rotated by rotating the handle, particularly when the rotational torque of the spiral shaft changes when the fishing line guide portion or the slider is returned at both ends of the spiral shaft, the annular member made of the elastic body is attached to the spiral shaft. Since there is no rattling between the mounting portion and the mounting recess of the gear part, the angler can perform a smooth handle operation. For this reason, it can suppress that the sensory sensor's handle operation falls.

The gear part mounting structure which concerns on this invention 2 is a gear part mounting structure of invention 1 WHEREIN: The spiral shaft is formed in the recessed recess along the outer periphery of a mounting part, and further has a mounting groove in which an annular member is mounted. In this case, the mounting groove can be easily prevented from falling out and positioning the annular member.

The gear part further has an engagement recess formed in communication with the tip end side of the mounting recess so as to have a small diameter and engaged with the engagement portion. In this case, by engaging the non-circular engagement portion with the non-circular engagement recess, the mounting portion can be mounted in the mounting recess in a relatively non-rotating manner.

The gear part mounting structure which concerns on this invention 4 is formed in the gear part mounting structure in any one of invention 1-3, The mounting part is formed so that the cross-sectional shape of an axial direction may be circular. The mounting recess is formed such that the cross-sectional shape in the mounting direction of the mounting portion is slightly larger in diameter than the mounting portion. In this case, for example, when the mounting portion and the mounting recess have a circular fitting dimension, the spiral shaft and the gear part can be pulled out with a simple configuration, so that the accuracy of the concentricity is improved. Can be kept high.

As for the gear component mounting structure which concerns on this invention 5, in the gear component mounting structure in any one of invention 1-4, the annular member is an O-ring. In this case, the O-ring can provide an annular member of low cost.

The gear part mounting structure which concerns on this invention 6 is a gear part mounting structure in any one of invention 1-5, The reciprocating mechanism of a fishing reel is an oscillating mechanism of the spinning reel for moving back and forth with a spool shaft. In this case, in the oscillating mechanism of the spinning reel, it is possible to suppress the deterioration of the sense of the angler's handle operation.

The cylindrical portion 30, the first rotor arm 31 and the second rotor arm 32 are made of, for example, aluminum alloy and are integrally formed.

The first rotor arm 31 is convexly curved outwardly from the cylindrical portion 30 and extends forward, and a connection portion with the cylindrical portion 30 is formed in the cylindrical portion 30. It is wide and curved in the circumferential direction. On the outer circumferential side of the front end of the first rotor arm 31, the first veil support member 40 is rotatably mounted. At the tip of the first bale support member 40, a line roller 41 for guiding the fishing line to the spool 4 is attached.

The second rotor arm 32 is convexly curved outwardly from the cylindrical portion 30 and extends forward, and the connection portion with the cylindrical portion 30 is widened and curved in the circumferential direction of the cylindrical portion 30. On the outer periphery side of the tip of the second rotor arm 32, a second veil support member 42 is mounted so as to be swingable.

Between the line roller 41 and the 2nd bail support member 42, the bail 43 of the shape which curved the wire rod in substantially U shape is being fixed. The bail arm 44 which guides a fishing line to the spool 4 is comprised by these 1st bail support member 40, the 2nd bail support member 42, the line roller 41, and the bale 43. As shown in FIG. The bale arm 44 is swingable between the row guide posture shown in FIG. 2 and the inverted row open posture.

As shown in FIG. 2, the spool 4 is disposed between the first rotor arm 31 and the second rotor arm 32 of the rotor 3. The spool 4 is, for example, a large and small two-stage cylindrical member obtained by forging a aluminum alloy, and includes a normal winding body portion 4a in which a fishing line is wound around the outer circumference, and a winding body portion ( A large diameter ordinary skirt portion 4b integrally molded at the rear portion of 4a) is provided.

As shown in FIG. 2, the rotor drive mechanism 5 includes a face gear 11 that rotates together with a handle shaft 10 to which a handle 1 is connected, and a pinion gear that meshes with the face gear 11. 12) The pinion gear 12 is normally formed, the front part of the pinion gear 12 penetrates through the center of the rotor 3, and is fixed to the rotor 3 by the nut 13. The pinion gear 12 is rotatably supported by the reel main body 2 via the bearing 14a, 14b in the middle part and the rear end of the axial direction, respectively. The front part of the pinion gear 12 is formed with the parallel chamfer of predetermined length. The chamfer portion of the pinion gear 12 is formed to rotatably connect the rotor 3 to the pinion gear 12.

As shown in FIG. 2, the oscillating mechanism 6 moves the spool shaft 15 connected to the center of the spool 4 via the drag mechanism 8 in the front-rear direction to move the spool 4 in the same direction. It is a mechanism for moving. The oscillating mechanism 6 is moved in the front-rear direction along the spiral shaft 16 and the spiral shaft 16 which are arranged parallel to the lower side of the spool shaft 15 and have a spiral groove 16a formed on the outer circumference. The slider 17, the intermediate gear 18 fixed to the distal end of the spiral shaft 16, and the two guide shafts 19a on which the slider 17 is movably mounted and arranged in parallel with the spiral shaft 16. 19b) (only the guide shaft 19a is shown in FIG. 2) and the elastic body mounted between the mounting portion 16c of the spiral shaft 16 and the mounting recess 18c of the intermediate gear 18 which will be described later. It has the annular member 20. The rear end of the spool shaft 15 is fixed to the slider 17 so as not to rotate. The intermediate gear 18 rotates in conjunction with the rotor drive mechanism 5 and meshes with the pinion gear 12 via a reduction mechanism not shown. Here, by the deceleration mechanism (not shown), the forward and backward movement speed of the oscillating mechanism 6 is slowed down, thereby realizing full-scale winding of the fishing line tightly on the spool 4.

As shown in FIG. 3 in an enlarged manner, the spiral shaft 16 includes a shaft main body 16b, a spiral groove 16a formed at both ends thereof to intersect the outer periphery of the shaft main body 16b, and a shaft main body ( The end portion of the mounting portion 16c provided at one end (front end, left end in Figs. 2 and 3) of 16b and the distal end portion of the mounting portion 16c in a small diameter and in the axial direction so as to be non-circular. The formed engaging portion 16d and the mounting groove 16e are formed by being recessed along the outer periphery of the base end of the mounting portion 16c and to which the annular member 20 is mounted. The shaft main body 16b is a cylindrical shaft member extending in the front-rear direction, and the front-rear end of the shaft main body 16b is rotatably supported by the front wall part and the rear end wall part formed in the inside and the rear end of the reel body 2a. The mounting portion 16c is formed so that the cross-sectional shape in the axial direction is circular. The engaging portion 16d is formed such that the distal end of the mounting portion 16c has an elliptical cross-sectional shape in the axial direction. Since the mounting groove 16e is an annular groove that is slightly shallower than the thickness of the annular member 20, when the annular member 20 is mounted, the outer circumferential portion of the annular member 20 protrudes outward from the outer circumference of the mounting portion 16c. It is supposed to.

The slider 17 has an engagement member (not shown) engaged with the spiral groove 16a therein and reciprocates in the front-rear axis direction by the rotation of the spiral shaft 16. The slider 17 is fixed to the rear end of the spool shaft 15 so as not to rotate. The slider 17 is guided in the front-rear direction by the two guide shafts 19a and 19b.

As shown in FIG. 3, the intermediate gear 18 includes a gear main body 18a, a gear tooth 18b formed along the circumferential direction of the outer circumference of the gear main body 18a, and an inner circumferential side of the gear main body 18a.

It has the engagement recessed part 18d. The mounting recess 18c is formed such that the mounting direction cross-sectional shape of the mounting portion 16c is slightly larger in diameter than the mounting portion 16c, and the mounting portion 16c and the mounting recess 18c have a circular fitting dimension. . The engagement recessed part 18d is formed so that cross-sectional shape may be elliptical, and the engagement part 16d is attached so that rotation is impossible.

As shown in FIG. 3, the annular member 20 is an O-ring made of an elastic body that is interposed between the mounting portion 16c and the mounting recess 18c. The annular member 20 is an O ring made of synthetic rubber having elasticity such as nitrile rubber (NBR) or styrene butadiene rubber (SBR). The annular member 20 is elastically mounted in the mounting groove 16e formed in the mounting portion 16c, and the outer circumferential portion protrudes outward from the outer circumference of the mounting portion 16c. As a result, since the outer circumferential surface of the annular member 20 contacts the inner circumferential surface of the mounting recess 18c with elastic force, there is no rattling between the mounting portion 16c and the mounting recess 18c.

The operation and operation of such a spinning reel will be described.

At the time of casting, first, the bale arm 44 is inverted to a string opening position. As a result, the first veil support member 40 and the second veil support member 42 swing. In this state, the fishing rod is cast while hooking the fishing line with the index finger of the hand holding the fishing rod. The fishing line is then vigorously released by the weight of the gear. When the handle 1 is rotated in the file winding direction in this state, the rotor 3 is rotated in the file winding direction by the rotor drive mechanism 5, and the bale arm 44 is turned by the bale reversing mechanism (not shown). Returning to the guide position, the fishing line is wound around the spool 4. At this time, the spool 4 is moved back and forth by the oscillating mechanism 6 interlocked with the rotor drive mechanism 5 so that the fishing line is uniformly wound. Specifically, the rotation of the pinion gear 12 of the rotor drive mechanism 5 is transmitted to the intermediate gear 18 via a deceleration mechanism (not shown) of the oscillating mechanism 6. When the intermediate gear 18 rotates, the spiral shaft 16 which is rotatably mounted to the intermediate gear 18 rotates so that the slider 17 moves in the front-rear direction. Then, the spool shaft 15 fixed to the slider 17 moves back and forth, and the spool 4 moves back and forth.

In this spinning reel, the annular member 20 made of an elastic body is mounted between the mounting portion 16c of the spiral shaft 16 and the mounting recessed portion 18c of the intermediate gear 18, so that the mounting portion 16c is mounted. When it mounts to the recessed part 18c so that relative rotation is impossible, rattling will not occur between the mounting part 16c and the mounting recessed part 18c. Therefore, when the intermediate gear 18 is rotated by rotating the handle 1, the rotational torque of the spiral shaft 16 has changed, particularly when the slider 17 is returned at both ends of the spiral shaft 16. Even when the elastic member annular member 20 is attached, there is no rattling between the mounting portion 16c and the mounting recess 18c, so that the angler can perform a smooth handle operation. For this reason, it can suppress that the sensory sensor's handle operation falls.

In addition, in the conventional structure, although the helix shaft 16 and the intermediate gear 18 are prevented from rattling, both have been caulking fixed or adhesive fixed, but in this case, especially spinning reel In the case of the oscillating mechanism 6, assembly may be difficult. In particular, in the case of caulking the spiral shaft 16 and the intermediate gear 18, there is a possibility that the concentricity and the right angle are not accurate. On the other hand, in the structure of this invention, since the annular member 20 of an elastic body is attached between the mounting part 16c of the spiral shaft 16, and the mounting recessed part 18c of the intermediate gear 18, both This eliminates caulking and eliminates the defect that the assembling of the spiral shaft 16 and the intermediate gear 18 becomes difficult or the concentricity or the squareness is not accurate.

As shown in FIG. 4, the bearing reel employing another embodiment of the present invention includes a reel main body 101, a handle 102 for spool rotation disposed on the side of the reel main body 101, and a handle. The star drag 103 for drag adjustment arrange | positioned at the reel main body 101 side of the 102 is provided. In the reel main body 101, a spool 104 and a level winding mechanism 106 for winding a fishing line uniformly on the spool 104 are disposed. In addition, a gear member 118 for transmitting the rotational force from the handle 102 to the spool 104 and the level wind mechanism 106 is disposed in the storage space on the right side of the reel unit 101.

The level winding mechanism 106 includes a spiral shaft 116 having a spiral groove 116a intersecting an outer circumferential surface thereof, and a fishing line guide 117 reciprocating in the spool shaft direction by the spiral shaft 116 to guide the fishing line. Have. Both ends of the spiral shaft 116 are rotatably supported by both side plates of the reel unit 101. The gear member 118 mentioned above is attached to the right end of the spiral shaft 116, and rotation of the handle 102 is transmitted to the spiral shaft 116 via the gear member 118. As shown in FIG. An annular member 120 made of an elastic body is mounted between the mounting portion 116c of the spiral shaft 116 and the mounting recess 118c of the gear member 118. In addition, since the specific structure of the spiral shaft 116, the gear member 118, and the annular member 120 is the same as that of the spiral shaft 16, the intermediate gear 18, and the annular member 20 of the said Example, it abbreviate | omits. do.

When it mounts in the mounting recessed part 118c so that relative rotation is not possible, rattling does not arise between the mounting part 116c and the mounting recessed part 118c. Therefore, when the gear member 118 is rotated by rotating the handle 102, in particular, when the fishing line guide 117 is returned at both ends of the spiral shaft 116, the rotational torque of the spiral shaft 116 is increased. Even when it changes, since the rattling between the mounting part 116c and the mounting recessed part 118c is eliminated by attaching the annular member 120 of an elastic body, an angler can perform a smooth handle operation. For this reason, it can suppress that the sensory sensor's handle operation falls.
